regex - matchesInString function returning an empty Array in Swift -



regex - matchesInString function returning an empty Array in Swift -

i have code working in objective-c

nsregularexpression* regex = [[nsregularexpression alloc] initwithpattern:@"(.*?)(<[^>]+>|\\z)" options:nsregularexpressioncaseinsensitive|nsregularexpressiondotmatcheslineseparators error:nil]; nsarray* results = [regex matchesinstring:text options:nsmatchingreportprogress range:nsmakerange(0, text.length)];

but swift version not working. matchesinstring returning empty array (using same tagged text in both cases)

let regexoptions = nsregularexpressionoptions.caseinsensitive | nsregularexpressionoptions.dotmatcheslineseparators allow regex = nsregularexpression.regularexpressionwithpattern("(.*?)(<[^>]+>|\\z)", options: regexoptions, error: nil) var results = regex.matchesinstring(markuptext, options: nil, range: nsmakerange(0, countelements(markuptext))) array<nstextcheckingresult>

even though documentation states matchesinstring returns array of nstextcheckingresult, noted in objective-c code (that works) array contains nssimpleregularexpressioncheckingresult objects , not nstextcheckingresult objects. empty array reported in swift version reports 0 nstextcheckingresult objects though

any thought of missing here?

update, works me:

let regexoptions:nsregularexpressionoptions? = nsregularexpressionoptions.caseinsensitive var matchingerror : nserror? allow regex = nsregularexpression(pattern: "(.*?)(<[^>]+>|\\z)", options: regexoptions!, error: &matchingerror) allow markuptext = "<html></html>" allow results = regex.matchesinstring(markuptext, options: nil, range: nsmakerange(0, countelements(markuptext))) array<nstextcheckingresult>

i not sure why regexoptions has optional. may bug in compiler.

older thoughts

this may bug in xcode6b2. simplified illustration 1 line:

let regexoptions = nsregularexpressionoptions.caseinsensitive

and error:

fatal error: can't disclose optional.none

i file bug this.
